+# TinyGo Benchmarks
+
+This directory contains multiple benchmarks compiled with TinyGo to WebAssembly.
+
+TinyGo is a Go compiler designed for small places, producing compact
+WebAssembly binaries suitable for resource-constrained environments.
+
+## Benchmarks
+
+### tinygo-json.wasm
+JSON serialization and deserialization using Go's `encoding/json` package.
+- Input: ~2.1MB JSON file with 100 user records
+- Tests: Parse and stringify operations
+
+### tinygo-regex.wasm
+Regular expression matching using Go's `regexp` package.
+- Input: ~6.5MB text corpus (same as `benchmarks/regex/default.input`)
+- Tests: 3 regex patterns (emails, URIs, IPs) matching the Rust benchmark
+
+## Building
+
+From the `benchmarks` directory:
+
+```bash
+./build.sh tinygo/
+```
+
+## Adding New Benchmarks
+
+To add a new TinyGo benchmark, create a new directory containing `main.go`,
+`go.mod`, `default.input`, and expected output files. The build script will
+automatically discover and build it.
